I feel there is an opportunity to improve the licensing portion in the git lesson by briefly mentioning perhaps in one sentence the value of asserting copyright, and the fact that a copyright statement is frequently included in the LICENSE file. I found it surprising that the page mentions copyright holders suing you, but doesn't mention the importance of explicit copyright assertion.

I am not a lawyer and cannot give legal advice, but perhaps some general statement about the value of explicit copyright and the opportunity to address that issue in the LICENSE file would improve the page.
